text: Patch-Clamp Electrophysiology was developed by Neher and Sakmann in 1976. This technique allowed measurements of individual proteins through ion channels. A glass pipette was fixed to the cell membrane, and the ion currents though the ion channels were measured. The Patch-Clamp method increased the sensitivity of detection by three orders of magnitude over previous methods, and the time resolution for the measurements was decreased to nearly 10 microseconds. The success of this method was a result of the ability to create a high resistance seal between the glass micropipette and the cell membrane; isolating the system chemically and electrically.
